我正在尝试将我的供应商和应用包与autodll-webpack-plugin(v0.4.2
)分开。此软件包是webpack的DllPlugin上的顶级插件,add-asset-html-webpack-plugin用于自动排序index.html
中的导入。
这个插件应该做的是分离供应商库和应用程序代码。我可以使用webpack中的CommonsChunkPlugin执行此操作,但这样就可以在每次重新编译时重新生成包。这比生成供应商包一次效率低,只在更改库时重新编译它。
问题
我有这个插件去工作" (它输出vendor.bundle.js
)。这里唯一的问题是当我用webpack-bundle-analyzer(app.bundle.js
)检查v2.13.1
时。我可以看到vendor.bundle.js
中的所有node_modules也被加载到这个包中,因此该插件无法正常工作。
版本
我正在使用:
v4.11.0
v7.1.4
v6.26.3
v0.4.2
项目结构
我的项目有以下文档结构:
App
-- build //Here are the output bundles located
-- node_modules
-- public
-- index.html
-- src // App code
-- webpack
-- webpack.common.js
-- webpack.dev.js
-- webpack.prod.js
-- package.json
我的webpack.common.js (此代码与Dev& prod版本共享)
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const AutoDllPlugin = require('autodll-webpack-plugin');
module.exports = {
entry: {
app: [
'babel-polyfill',
'./src/index.js',
],
},
output: {
filename: '[name].bundle.js',
path: path.resolve(__dirname, '../build'),
publicPath: '', // Is referenced by the autodll-webpack-plugin
},
module: {
rules: [
{
test: /\.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/,
options: {
plugins: ['react-hot-loader/babel'],
cacheDirectory: true,
presets: ['env', 'react'],
},
}
],
},
plugins: [
new HtmlWebpackPlugin({
template: './public/index.html'
}),
new AutoDllPlugin({
inject: true, // will inject the DLL bundle to index.html
debug: false,
filename: '[name]_[hash].js',
context: path.join(__dirname, '..'),
path: '',
entry: {
vendor: [
'react',
'react-dom'
]
},
}),
],
};
根据autodll-webpack-plugin
的{{3}},应使用上下文密钥进行分隔。所以我认为这就是问题所在。
文档描述你应该引用webpack.config.js
所在的文件夹,但我有3个,我需要引用哪一个?我在文档中看到的文件夹名为webpack
,而不是config
,..
在这里也是正确的吗?
答案 0 :(得分:1)
所以最后我没有让DLL设置工作。在阅读了一些之后,我意识到autodll-webpack-plugin的创建者建议改为使用hard-source-webpack-plugin,因为webpack可能会在将来用作默认选项。
在阅读了一些之后我也意识到不建议在生产中使用DLL插件,因为你必须重新编译它(dev build添加东西)。因此,您应该将hard-source-webpack-plugin
用于开发构建,将SplitChunksPlugin用于生产。
我很容易让这两个人工作:
<强> Webpack.dev.js 强>
const merge = require('webpack-merge');
const webpack = require('webpack');
const path = require('path');
const HardSourceWebpackPlugin = require('hard-source-webpack-plugin');
const common = require('./webpack.common.js');
module.exports = merge(common, {
mode: 'development',
devtool: 'eval-source-map',
devServer: {
hot: true,
contentBase: path.resolve(__dirname, 'build'),
historyApiFallback: true, // Allow refreshing of the page
},
plugins: [
// Enable hot reloading
new webpack.HotModuleReplacementPlugin(),
// Enable caching
new HardSourceWebpackPlugin({
cacheDirectory: '.cache/hard-source/[confighash]',
configHash: function(webpackConfig) {
return require('node-object-hash')({ sort: false }).hash(webpackConfig);
},
environmentHash: {
root: process.cwd(),
directories: [],
files: ['package-lock.json'],
},
info: {
mode: 'none',
level: 'warn',
},
}),
],
});
<强> webpack.prod.js 强>
const merge = require('webpack-merge');
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
const CleanWebpackPlugin = require('clean-webpack-plugin');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const common = require('./webpack.common.js');
module.exports = merge(common, {
mode: 'production',
plugins: [
// Clean the build folders
new CleanWebpackPlugin(['build'], {
root: process.cwd(), // Otherwise the 'webpack' folder is used
}),
//Make vendor bundle size visible
new BundleAnalyzerPlugin({
analyzerMode: 'static',
openAnalyzer: false,
reportFilename: 'stats/prod-report.html',
}),
],
optimization: {
splitChunks: {
chunks: 'all',
cacheGroups: {
vendor: {
name: 'vendor',
chunks: 'all',
test: /[\\/]node_modules[\\/]/,
},
},
},
minimizer: [
// Optimize minimization
new UglifyJsPlugin({
cache: true,
parallel: true,
uglifyOptions: {
ecma: 6,
mangle: true,
toplevel: true,
},
}),
],
},
});
我希望这对任何人都有帮助。
